Hello, I am using iPhone 6s Plus with Koodo's $55 for 2GB plan. I also have a Samsung Galaxy Note PRO 12.2 which has a phone capability and 4G supported. Can I just put the sim card in any device I like and whenever I want?

So far, I just use the 6s Plus. However, as I spend 3-4 hours/day to commute on the bus and subway, it would be easier for the eyes if I use a 12.2 device for browsing the web and reading pdf files.

It will not cost more. Tethering is free with Koodo. Unfortunately, you will use more data but not that much. Because most of the usage will be on your tablet instead of your phone. Your phone will use some data while idle for push notifications and things like that.

As for your second question, I do not know the answer. Why don't you try? I know Fido doesn't support that. Don't know bout Koodo.

Not much really. Visualize it as if your phone was idle and using normal data of an idle phone. I can't tell you exactly how much, but tethering data won't make you use significantly higher amount of data.

Just make sure your tablet has automatic update turned off (from Google Play store) because that will bust your data. The tablet won't know you're not on wifi and will still download the updates!

You're welcome. I've included a link to a video that shows how to setup a Wi-Fi hotspot. It's really the only option you have. Periodically monitor data usage to give yourself an idea of how much data is used while your tablet is tethered to your Wi-Fi hotspot.
